PURPOSE Categorizing patients with cancer by their disease stage can be an important tool when conducting administrative claims-based studies. As claims databases frequently do not capture this information, algorithms are increasingly used to define stage. To our knowledge, date, no study has algorithm categorize bladder (BC) (non–muscle-invasive BC [NMIBC], muscle-invasive [MIBC], or locally advanced/metastatic urothelial carcinoma [la/mUC]) in a US-based health care database. METHODS A was...
